Extended Data Fig. 9: Phylogenetic distribution and comparative morphology of a lateral exposure of the palatine (LEP) and the loss of the lacrimal in Temnospondyli.
From: Triassic stem caecilian supports dissorophoid origin of living amphibians
a, Phylogenetic topology (derived from refs. 14,55) with variable presence of the lacrimal and the LEP (See Supplementary Information 3 for further discussion of this feature). Comparative silhouettes of skulls in dorsal b–h and lateral i–k views; the prefrontal is coloured yellow here as it is the main element to positionally compensate for an absent lacrimal. b, The dvinosaur Thabanchuia oomie64 (Illustration reproduced with permission from Cambridge University Press from ref. 64). c, The amphibamid Doleserpeton annectens9 (Illustration adapted from ref. 9 under copyright © Society of Vertebrate Paleontology, www.vertpaleo.org, reprinted by permission of Informa UK Limited, trading as Taylor & Francis Group, www.tandfonline.com on behalf of Society of Vertebrate Paleontology, www.vertpaleo.org. d, The ‘dendrerpetid’ Dendrerpeton helogenes65, which represents the plesiomorphic condition (Illustration adapted from ref. 65. under copyright © Society of Vertebrate Paleontology, www.vertpaleo.org, reprinted by permission of Informa UK Limited, trading as Taylor & Francis Group, www.tandfonline.com on behalf of Society of Vertebrate Paleontology, www.vertpaleo.org). e, The trematosaur Wantzosaurus elongatus66. f, The dvinosaur Acroplous vorax67 (Illustration adapted from ref. 67 under copyright © Society of Vertebrate Paleontology, www.vertpaleo.org, reprinted by permission of Informa UK Limited, trading as Taylor & Francis Group, www.tandfonline.com on behalf of Society of Vertebrate Paleontology, www.vertpaleo.org). g, the rhytidosteid Laidleria gracilis68 (Illustration adapted from ref. 68. by permission of the Zoological Journal of the Linnean Society). h, Chinlestegophis jenkinsi14. i, Acroplous vorax67 in lateral view. j, Rileymillerus cosgriffi69 in lateral view. k, Chinlestegophis jenkinsi14 in lateral view. The prefrontal is also coloured yellow here as it is the main element to positionally compensate for an absent lacrimal. Silhouettes are not to scale.
